Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed June 7, 1920. Serial No. 387,084.

Z '0 all whom it may concern Be it known that I, Lnrrin VALIRIANonrrrmor, a citizen of the United States, residing at Fort Cobb, in thecounty of Caddo and State of Oklahoma, have invented certain new anduseful Improvements in Thermometer-Holders, of which the following is aspecification.

This invention relates to thermometer holders for incubators.

The object of the invention is to provide a simple and eiiicient deviceof this character which will reliably yet detachably support athermometer bulb in contact with an egg Without displacing the eggs andwhich cannot be overturned by the chicks when hatching takes place.

Another object is to so construct such a holder which after beingmounted on the screen which supports the egg tray may remain therethroughout the period of incubation and which is equipped with means fordetachably supporting a thermometer so that the thermometer may beeasily applied and removed without disturbing the eggs.

With these and other objects in view, the invention consists in certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claims, and in the drawingsillustrative of the preferred embodiment of the invention.

In the accompanying drawings:

Figure 1 represents a side elevation of this improved holder shownapplied with the incubator screen and egg tray in section.

Fig. 2 is a rear elevation thereof.

Fig. 8 is a transverse vertical section taken on the line 33 of Fig. 1.

Fig. i is a top plan view of a portion of an incubator screen with thisimproved attachment shown applied, and,

Fig. 5 is a perspective view of the attachment detached and having thethermometer shown mounted therein in dotted lines.

In the embodiment illustrated an incubator screen of ordinaryconstruction is shown at S with an egg tray T mounted thereon. Thethermometer holder 1 constituting this invention is shown applied to thescreen S and is composed of sheet metal preferably of. aluminum and isstruck out from a single piece of metal comprising a standard 2 having afoot 3 projecting at i right angles from its lower end and having on itsside edges laterally extending gripping fingers i equipped withdownturned terminals 5 which are designed to be assed through the meshesof the screen and clamped thereunder as is shown clearly in Figs. 1 and4.

The standard 2 has its upper end extended outwardly and upwardly to forman inclined arm 6 which is folded inwardly upon itself at 7 theoverlying portion 8 being provided with upstanding struckout springgripping fingers 9. These fingers 9 are arranged in staggered relationand are designed to receive between them the thermometer Z which may beof any ordinary construction such as is employed in connection wlthincubators.

This improved holder is designed to be mounted at one side of the eggtray T so that the tray may be removed when desired without interferingwith the holder and which also provides for the positioning of thethermometer between two eggs with its bulb B in contact with one of theeggs which is necessary to obtain the best results enabling the operatorto determine the exact temperature of the eggs.

From the above description. it will be obvious that this holder 1 whenmounted on the screen S by clamping the fingers 4 thereof around andunder the screen wires will be reliably held against all possibility ofits beingoverturned by the chicks when hatching and yet will permit thethermometer to be removed and applied at the will of the operatorwithout in any way interfering with the eggs.

The preferred embodiment of the invention is disclosed in the drawingsand set forth in the specification, but it will be understood that anymodifications within the scope of the claims may be made in theconstruction without departing from the principle of the invention orsacrificing any of its advantages.

V7 hat is claimed is:

1. A device of the class described comprising a support engaging basewith a stand ard arising therefrom and having an upwardly and outwardlyinclined arm at its upper end provided with a folded downturned portionhaving spring fingers to support a thermometer.

2. A device of the class described comprising a standard having means atone end to secure it to a support, and an upwardly and outwardlyinclined laterally extending arm 2 menses equipped with downturnedfingers on its 10 side edges, the upper end of said standard being bentlaterally outward and upward and folded inwardly upon itself, theoverlying portion being equipped with outstruck upstanding springfingers.

In testimony whereof, I aflix my signature hereto LETTIE VALIRIANORTHROP.
